Study model fit.

To provide empirical support for understanding the effects of different family parenting styles on the development of preschool children’s eating habits and to promote healthy child development. Using a randomized whole-group sampling method, full-time public kindergartens in three regions of China were selected as the study population of preschool children, and 1141 children’s guardians in these regions were surveyed and evaluated. It was used to examine the differential effects of different family parenting styles (EMBU) on preschool children’s eating behavior (CEBQ), while quality of survival (QLSCA) and nutritional literacy (NLS) played a mediating role in the process. The results showed that at the direct effect level, authoritative, authoritarian, coddling, and neglectful family parenting styles had significant effects on preschool children’s eating behavior (-0.161 ≤ β ≤ 0.232, p < 0.05); at the indirect effect level, family survival quality (QLSCA), and nutritional literacy (NLS) under the influence of different family parenting styles (EMBU) on children’s eating the total indirect effect was [OR] 0.273, 95%: CI 0.181–0.368. It is evident that it is imperative to develop good eating behaviors in children at preschool age.
